XO Performance Rotors

BuyBrakes.com presents our value-priced XO Brand drilled-and-slotted discs that allows you to finally replace your original rotors with performance rotors for a fraction of the usual cost. Featuring both precision chamfered drilling and slotting on both sides of the rotor, the brake pads come into contact with a stronger initial bite that allows to come down from speed quicker than a smooth-faced rotor. With the rotors being vented just like you’ve seen on high-end European cars and racecars, they’ll run cooler and prevent warping typically associated with stock OEM rotors.

You’ll find our superb pricing typically beats even the auction based websites trying to move unknown brand products from unheard of companies. So take a look at our application chart (updated monthly) and see if we have XO Rotors available for your vehicle. You’ll love the fact you don’t have to pay high prices for performance rotors and pads to match.

XO Performance Cross-Drilled and Rotor Information

12 Month or 12,000 mile warranty when XO Rotors are combined and purchased at the same time with PowerStop Evolution Ceramic Pads

• Machined in the USA
• 98% of orders shipped within 2 days
• Brake rotor castings are made using SAEJ431 metallurgy from ISO9000 registered foundries
• Brake rotor blanks are made using the finest G3000 grade castings
• Each hole is countersunk for a smooth linear transition at the edge. This reduces stress risers for improved durability.
• Holes are engineered for optimum cooling to prevent rotor warping
• Zinc-dichromate plating resists rust for years and it provides much better protection than painted brake rotors
• Precision machined using state of the art CNC machine for perfect fit and balance
• Custom chamfered holes to prevent brake rotor cracking

The Science Behind Faster Stops!

Cross-drilled rotors can improve stopping power up to 35% over stock rotors as reported in SAE Technical Paper 2006-01-0691 "The effect of Rotor Crossdrilling on Brake Performance" by two GM engineers. That's why Corvette, Porsche, Mercedes, and BMW vehicles come factory direct with drilled brake rotors. i.e. not just dimpled. The fact is that the drill holes greatly improve convection heat transfer and the result is more brake pad bite. The report also states that "it is possible to have too many holes, in which case too much cooling air would be lost before reaching the hottest part of the rotor". XO Performance brake rotors are designed for optimum brake rotor cooling and durability with one cooling hole per vane. This also provides superior strength to avoid brake rotor cracking.

Stop Rotor Warping!

High brake rotor temperature can cause heat spots to form on the brake rotor, and this causes pulsating brakes. Cross-drilled rotors keep the brakes up a 150° cooler to prevent brake rotor warping.
